monitor session
monitor session
Use the
monitor session
global configuration command on the switch stack or on a standalone switch
to start a new Switched Port Analyzer (SPAN) session or Remote SPAN (RSPAN) source or destination
session, to enable ingress traffic on the destination port for a network security device (such as a Cisco
IDS Sensor Appliance), to add or delete interfaces or VLANs to or from an existing SPAN or RSPAN
session, and to limit (filter) SPAN source traffic to specific VLANs. Use the
no
form of this command
to remove the SPAN or RSPAN session or to remove source or destination interfaces or filters from the
SPAN or RSPAN session. For destination interfaces, the encapsulation
options are ignored with the
no
form of the command.

Syntax Description
session_number
Specify the session number identified with the SPAN or RSPAN session.
The range is 1 to 66.
destination
Specify the SPAN or RSPAN destination. A destination must be a physical
port.
interface
interface-id
Specify the destination or source interface for a SPAN or RSPAN session.
Valid interfaces are physical ports (including type, stack member, module,
and port number). For
source interface
,
port channel
is also a valid
interface type, and the valid range is 1 to 64.
encapsulation replicate
(Optional) Specify that the destination interface replicates the source
interface encapsulation method. If not selected, the default is to send
packets in native form (untagged).
These keywords are valid only for local SPAN. For RSPAN, the RSPAN
VLAN ID overwrites the original VLAN ID; therefore, packets are always
sent untagged.
ingress
(Optional) Enable ingress traffic forwarding.
dot1q vlan
vlan-id
Accept incoming packets with IEEE 802.1Q encapsulation with the
specified VLAN as the default VLAN.
isl
Specify ingress forwarding using ISL encapsulation.
